hyperbolic paraboloid

A hyperbolic paraboloid is a three-dimensional shape that looks like a saddle, curving upward in one direction and downward in another. It can be described mathematically by a specific quadratic equation. This surface is common in architecture and engineering because of its strength and aesthetic appeal. It’s a doubly ruled surface, meaning it can be formed with straight lines, which makes construction easier. Its unique shape allows it to efficiently distribute stress, making it both functional and visually striking in structures like roofs and bridges.
